上面的这篇文章中介绍了很多css3的动画效果,这里节选其中的打字效果

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html" charset="utf-8" />
<title>Font Step Show</title>
<style type="text/css">
@-webkit-keyframes typing { from { width: 0; } }
@keyframes typing { from { width: 0; } }
@-webkit-keyframes cursor { 50% { border-color: transparent; } }
@keyframes cursor { 50% { border-color: transparent; } }
.text {
	width: 0;
	border-right: .1em solid;
	overflow: hidden;
	font: 5em monospace;
	margin-top: 50px;
	-webkit-animation: cursor 1s step-end infinite;
	animation: cursor 1s step-end infinite;
}
#go:target .text {
	width: 6.6em;
	width: 11ch; /* Number of characters */
	-webkit-animation: typing 8s steps(11),cursor 1s step-end infinite;
	animation: typing 8s steps(11),cursor 1s step-end infinite;
}
a {
	padding: 5px 10px;
	background: blue;
	color: #fff;
	border-radius: 8px;
	text-decoration: none;
	font: .9em Arial;
	margin-top: 10px;
	display: inline-block;
}
a:hover {
	opacity: 0.6;
}
</style>
</head>

<body>
<div id="go">
<a href="#go">Start</a>
<a href="#reset">Reset</a>
<p class="text">smashingmag</p>
</div>
</body>
</html>

<p class=”text”></p>

中的字数必须和css中steps()中的值一致,

动画cursor是鼠标一闪一闪的效果

动画typing是字一个一个出现的效果
